🔐 Privacy Policy – Class Timetable
This policy explains how the Class Timetable & Homework mobile app ("the App"), developed by Sogepps, handles data.
In short
- The app has no account or sign-in and no server of our own; as the developer we cannot access your data. It shows ads through Google AdMob, offers one optional one-time in-app purchase ("Remove ads") and needs an internet connection to load ads.
- Your timetables, courses, homework, exams, attendance records, grades and settings are stored only on your phone and are never sent to us.
- You export backup files, the timetable wallpaper (PNG), the PDF and CSV files yourself; they go only to the app or folder you choose in Android's share menu.
- The app uses the notification permission only to remind you of classes, homework and exams (optional). It does not ask for camera, location, microphone, contacts or storage permissions.
- Uninstalling the app or clearing its data deletes all your records. In case you lose your phone, share a backup file now and then.
1. We don't collect personal data
We (Sogepps), the developer of Class Timetable, do not collect your personal data, do not store it on our own servers and do not share it with anyone. The only data handled outside your device is the ad-related data Google processes under its own policy (see section 5); we do not receive it.
2. Information that stays on your device
The timetables you create (names, bell schedules, days), courses (names, teachers, rooms), homework, exams, attendance records, grades and credits, your own letter table and settings are stored only on your phone, in the app's local storage. This information is never sent to us. Every day the app makes an automatic backup copy on your phone (the last 14 days are kept); these copies also stay in the app's own folder.
If Android's device backup is turned on on your phone, Android may back up the app's data to your Google account under its own rules. Android does this, not us; we cannot access that backup and we do not see your data.
3. Files you export
You export backup files, the timetable wallpaper (PNG), the A4 PDF and the course list (CSV) yourself. They go only to the app or folder you choose in Android's share menu (for example a messaging, email or file app). The files contain only what you entered. How the apps you share with handle your data depends on their own privacy policies.
When you restore a backup, the app opens only the file you choose.
4. Permissions
Notifications: optional, used only to remind you of classes, homework due dates and exams, and only when you switch reminders on; the app keeps working if you decline. To show notifications on time and to schedule them again when the phone restarts, the app also uses Android's alarm scheduling, boot-completed, wake-lock and vibration permissions. It does not ask for camera, location, microphone, contacts or storage permissions. For ads, the connection check and the purchase the app also declares these permissions: INTERNET and ACCESS_NETWORK_STATE (to load ads and check the connection), com.google.android.gms.permission.AD_ID (advertising ID, used for ads) and com.android.vending.BILLING (Google Play purchase).
5. Ads and purchases
The app shows interstitial (full-screen) ads through Google AdMob (Google Mobile Ads SDK), only at natural breaks (for example after you share or export a file or close a screen) and at most about once every 3 minutes. In the EEA, UK and Switzerland, Google's consent message (UMP, User Messaging Platform) asks for your consent first; you can change that choice at any time under "Ad privacy options" in the app's Settings. Google/AdMob may collect and process your advertising ID, device and app information, IP address (and the approximate location derived from it), ad interactions and crash/diagnostic data to deliver, measure and personalise ads and to prevent fraud, under Google's own privacy policies: <a href="https://policies.google.com/privacy">Google Privacy Policy</a> and <a href="https://policies.google.com/technologies/partner-sites">how Google uses information from sites or apps that use its services</a>. You can reset or delete your advertising ID in Android settings. The app also offers one optional one-time in-app purchase, "Remove ads", through Google Play Billing. Google processes the payment; we (Sogepps) never receive your card or payment details. The app only checks with Google Play whether the purchase is owned. The ads are general-audience ads (content rating PG).
6. Internet access
The app needs an internet connection, to load ads and to check the connection (it checks whether www.gstatic.com and sogepps.tr are reachable). Without a connection it shows a "connection required" screen. We have no server that stores your data: your timetables, courses, homework and grades stay only on your phone and are never sent to us.
7. Children
Class Timetable is aimed at users aged 13 and over (13–15, 16–17 and 18+) and is not directed at children under 13; we do not knowingly collect personal data from children under 13.
8. Data deletion
All of your data stays on your device. You can delete your records permanently by uninstalling the app, by clearing the app's data in your Android settings, or with "Delete all data" in the app's menu; single timetables, courses and entries can also be deleted in the app. There is no data on our servers to delete. Backups and files you exported earlier are outside the app, so you must delete them yourself; for a copy kept in an Android backup, use your Google account's backup settings.
